Military Dictionary and Gazetteer
The lines followed by an army in making a strategical movement are called “strategical lines.” Temporary lines of operations, or manœuvre lines, therefore, are strategical lines. Lines of operations are important strategical lines. And in general, lines connecting two or more strategical points, which lines can be used by an army, and which allow of easy communication between these points, are “strategical lines.” A base of operations is therefore a strategical line.—Prof. J. B. Wheeler.
